The only really annoying boss in the entire Dungeon. The fight has 3 phases, in all three you want to tank her in the middle of the area. Phase 1. She uses two abilities. First she targets 3 players with a telegraph centered on themselves, doing a nasty DoT, that explodes after a short while leaving a flaming zone on the floor. The targetted players should run away from the boss and try and place the flaming zone where it won't impede them during the fight. It can be cleansed, but that drops the zone immediately which can cause issues. Second she targets one person, tethers them, places a flaming zone under their feet for the duration of the tether and then fires repeated, cone-shaped, flame attacks at them. CC break drops this, but most of the damage can be healed through and it means the rest of the group can dps her unimpeded , especially if the tank gets targeted, he should just avoid the telegraphs until the tether wears off. At about 800k life she transitions by targeting each player with a flame geyser dropping them to low health (not below 1hp) then she starts to call on molten waves for about 30 seconds, each wave starts from the back wall and crosses the entire zone with a small safe corridor which you can run through (they hurt a lot if they hit you). Once the last wave passes her, it's on to phase 2. Phase 2. Virtually identical to phase 1, stops at about 350k life and she once again uses flame geyser and molten waves for 30 seconds. Phase 3. In this phase instead of the tether attack, she calls a molten wave from one of 4 directions, you get a warning in the UI about the ground rumbling/shaking, pay attention and move to the safe corridor; once through, get her back to the middle as fast as possible else the next wave could surprise you. She still targets 3 players with flame zone telegraphs so the area will gradually fill the flame zones (most centered in/around the safe corridors through the molten waves), this is the dps race of the fight. We did not spot any interrupt points, she seemed to have infinite interrupt armour for the entire fight. Currently, you can run to the south wall during the transition phases, jump onto the ledge and avoid the molten waves entirely, this will likely be fixed soon. Even using this, in the transition to phase 3 the first molten wave can spawn directly under where players drop back down to the fight (if she uses molten wave early) killing them almost instantly.
